The iWISE PET series is ideal for any type of installation where pets are concerned thanks to Rokonet's Variable Pet Thresholding (VPT) Technology. Move to the iWISE series of cutting edge professional detectors, the wisest choice for your customer's peace of mind and your bottom line!

Lens Design
The iWISE PET lens is designed to reduce signals from pets while assuring catch performance of intruders. The upper level is much more sensitive than the lower ones, enhancing signals from upright intruders.

The lens design assures that the signal level from a pet will be lower than the signal level of an intruder, for a specific crossing frequency
of the detection fingers. In addition, the "active" creep zone ensures catch performance below the detector without compromising pet immunity.

VPT Algorithm
Due to the physics of the PIR sensor and optics, the PIR signal level depends on the crossing frequency of the detection fingers.

For example, an intruder with a high crossing frequency may have a lower signal level than a pet with a lower crossing frequency. Using a constant threshold may detect pets and ignore humans!

The VPT algorithm solves this by measuring the crossing frequency and selecting the correct threshold level for alarm accordingly, which is set above the pet signal and below the intruder level for each frequency. This is how VPT assures detection of intruders while ignoring pets.
